Kafka配置JAAS

Kafka配置JAAS

推荐本地测试使用，生产环境尽量使用KAFKA监听，或者将此类方法添加定时开关与生产者同步避免循环打印

public static void main(String[] args) {
        Properties props = new Properties();
        props.put(SaslConfigs.SASL_MECHANISM, "PLAIN");
        props.put("sasl.jaas.config","org.apache.kafka.common.security.plain.PlainLoginModule required username=\"***\" password=\"***\";");
        props.put("bootstrap.servers", "***");
        props.put("enable.auto.commit", "true");
        props.put("auto.commit.interval.ms", "1000");
        props.put("group.id", "***");
        props.put("session.timeout.ms", "60000");
        props.put("max.poll.records", 1000);
        props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
        props.put("value.deserializer","org.apache.kafka.common.serialization.StringDeserializer");
        props.put("security.protocol", "SASL_PLAINTEXT");
        props.put("sasl.mechanism","PLAIN");
        KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);
        consumer.subscribe(Arrays.asList("***"));
        //以下根据业务场景进行逻辑处理
        while (true) {
            long startTime = System.currentTimeMillis();
            ConsumerRecords<String, String> records = consumer.poll(1000);
            System.out.println(System.currentTimeMillis() - startTime);
            System.out.println("recieve message number is"+ records.count());
            for (ConsumerRecord<String, String> record : records) {
                System.out.printf("success" + "offset =%d,key =%s,value =%s,partition = %d %n",
                        record.offset(), record.key(), record.value(),
                        record.partition());
            }
        }
    }
